    I bet the heads that come with those Ebay 455 are junk "J" heads.
    Good luck finding Olds engines.
    When I worked at Jasper engines long ago I ran the blocks thru a cleaning solution and super heat cleaning and 3 out of 4 Olds blocks cracked and we threw them away for scrap so there aren't many around anymore.
    They mainly cracked all around the lifter bores and the outside water jackets along the sides of the bores.
    I had a 77 Indy pace car with a 403 and the crank and oil pan literally fell off the engine because it cracked so bad around the webbing around the crank.

    With any reman engine its source the cheapest parts possible and how fast can you do the machine work not how accurate. I recall a guy we built an engine for who had put 3 engines from Autozone in his pickup cause there was always something wrong. They replaced the bad engines for another one but he was on the hook for the R&R. He finally gave up and paid our price.

    I personally would never consider one of the weaker blocks like the 403. The cranks have material removed also and scare me for even a stock engine. As others have said, try to find a complete 455 so rust isn't an issue.

    I sure get what you mean on the reman stuff............ but strictly financially speaking, I'd buy the reman, pull it down and build it myself.

    I'm betting it would be money ahead to not have to refresh the whole block. Just swap pistons, maybe rods, and pick your own cam. Heads could be changed at any time, and you'd have good heads to sell then too.



    I bet it would work out the cheapest in the long run. Only machine work that would really benefit would be decking the block to match the pistons.

    if you're buying used - I'd sure feel better about getting something that is complete and has not been pulled apart - much less rust to deal with that way. Hopefully you can find a big old luxobarge in a yard that still has the hood and aircleaner in place- so the insides of the engine are still oil coated and hopefully have minimal rust.

    I know machine work isn't cheap - but I'm with you - I'd prefer to build my own and know what's there than spend the $$ for a reman'd unit.

    That was my train of thought too. I guess I just wanted to hear it from someone else. From what I've read (Bill Trovato's book), the 403 is only good for .030 over and anything (Olds) after 1975 has weak(er) main webs.

    It was just an option, that block is pretty rough, my concern are the lifter bores, they will most likely need to be sleeved, that is if you can get the lifters out........ And whatever it came out of the engine didn't turn, thus the reason the converter is still attached to the flywheel..... which makes you wonder what other surprises you'll find.........

    I guess if money isn't an object then you might be able to save this short block, but if it was me, I'd look for something a little more cleaner and that actually spins.........

    I've heard good and bad stories about remaned engines. Jasper is right up the road from here. I'd rather build it myself so I know what's inside, not mix and match to get it out the door. I've looked at what's currently listed on eBay too. Seems kinda price for not knowing condition, having to take someone's word on it. I haven't had a chance to roam the yards here yet either.

    For the amount of work and money that you'll put into that short block you might be better off buying one of these...... It comes with a 3 year/ 36,000 mile warranty which I don't think is bad for $3000 for the long block....... And it's a 455 at that!!!!.......

    started a topic opinions on block wanted

    opinions on block wanted

    I am looking for a rebuildable, and relatively unmolested, Oldsmobile motor. Ideally I'd like to find a 455 but would probably settle for a 403 if the circumstances were right. I'm not looking for anything wild, just a mild rebuild for a family ride.

    http://www.ebay.com/itm/180937795425...84.m1438.l2649









    I found this on eBay and would like some opinions before I pursue it. I've got my own impressions but want general feedback from people that know more about Oldsmobiles than I do (been studying hard though).
